MACHlNE FOR MAKENG BARB-LINK FENCING.

SPECIFICATION forming part of Letters Patent No. 292,408, dated January 22, 1884,

Application filed July 18, 1883.

To all whom it may concern:

Be it known that I, FRANK P. CADY, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Machines for Making Barb-Link Fencing, of which the following is a specification.

This invention relates to machines for making link or chain barb wire fencing automatically.

The nature of the invention will fully ap pear from the following description and the accompanying drawings, wherein Figure 1 is a plan view of the entire machine. Fig. 2 is a vertical transverse section upon the line 2 2 of Fig. 1. Figs. 3 and 1 are enlarged details of the mechanism for operating the clamping-jaws which seize the wire at each side of the coilers during the operation of the latter. Fig. 5 is a longitudinal vertical section of the machine upon the line 5 5 of Fig. 1. Fig. 6 is an enlarged vertical cross-section, showing the jaws whereby the cable is fed forward from the coilers. Fig. 7 is a detail of the bridge-piece. Fig. 8 is an elevation of the receiving end of the machine. Fig. 9 is a partial section enlarged, showing the devices for shaping the forward end of the linkblank at the first operation thereon. Fig. 9 is an enlarged horizontal section, showing the yield-guides which co-opcrate with the hook in one of the bending operations. Fig. 9" is a perspective of one of said guides. Fig. 10 is a detail of one of the benders. Figs. 11 and 12 are end views of the slotted mandrcls bearing the coiling-heads, and through which the link passes, that in Fig. 12 being the one which receives the link before the ends are coiled, and that in Fig. 11 being the final one, the link traveling through it after the ends have been coiled. Fig. 13 is a detail section of one of the feedingrolls, whereby the plain wire is fed at statedintervals and in proper lengths. Fig. 14 is a horizontal view, enlarged, of said rolls, the actuating-gearing be ing removedfor the sake of clearness. Fig. 15 shows the link-blank as it is left by the first bending operations at each end. Fig. 16 shows one blank at the end of the second bending, and another blank, the next preceding one, at the end of the third bending operation. Fig.

(MOdeL) 17 shows the completed cable, and also a link at the end of the third bending, and in readi ness for the ceiling of the points.

For the sake of perspicuity in my,description, I propose giving, as nearly as niay be in the order in which they occur, the various operations performed upon each link of the cablein its passage through the machine, and, as it is necessary to-mention at least three con secutive links, I distinguish the mostadvanced one by the letter A, the next in course by A, and the last by A. The end of the link which first enters the machine is also distinguished as x, and the other end as 7 The fencing is formed from a single wire, a, which is fed to the machine by continuouslyoperated mutilated rolls B. The rolls are loosely mounted upon shafts Bin juxtap osition to the gears B and are adjustable within certain limits around their respective shafts by means of the tightening-screws b and the circular slots b in said gears. If constructed as shown, these rolls will feed thelongest lengths of the wire when their bearingsurfaces exactly coincide; but'if it is designed to shorten the links, it may be done by adjusting one or the other of the rolls so that the bearing-surfaces will not bear upon the wire together until later, as illustrated at Fig. 14. This adjustability may be confined to one of the rolls,

and itis not necessary that the rolls and gears.

be placed together upon the shaft so long as the former are adjustable. One of the shafts Bis actuated from the main shaft C of the machine by gears C O, and said main shaft receives power from the drive-pulley C through the meshing of gears C and C. hen the wire a has been fed in the length necessary to form alink, such length is severed by the raising of the knife D, the stationary mate whereof is shown at D, said moving part being carried by the head D which is actuated from the main shaft by the crank I). A bending device, E, is carried by the same head with the knife, but is located the diameter of the wire below the surface of the knife, so the latter may complete blank, as shown at Fig. 15. The resistance necshape.

essary to effect this bend is afforded by a guide plate, E, located Over the wire, and having its vertical face, wherewith the point y comes in contact as the bend proceeds, beveled off, as in Fig. 1, to give said end an inclination laterally oblique to the vertical. This last feature is more fully explained hereinafter. At the same time the end 00 of the blank is carried up so as to stand nearly at right angles by a rising bending device, F, oscillated upon a pivot, F, by means of a pinion, f, upon said pivot, and a reciprocating rack, f, engaging with said pinion and actuated by the contact of a cam, F, upon the main shaft, with the roller f on the rack. A spring, f returns the rack after it has been forced upward by the cam. The body of the blank adjacent to the part thus bent is held down during this operation by the guide-plate G. This bender F lies, when not in operation, below the line of the feed, as shown ih Fig. 9, and partly under the stationary guide G, now to be described.

Before the completion of the bend last mentioned of the end as the extremity of said end is caught by the overhanging part of the stationary guide G, and as that bend proceeds it holds -said extremity down, so that by the time the bender F has reached the position shown in Fig. 8, and also in dotted lines in Fig. 9, a double bend willhave been imparted to this end of the blank. At this time the blank has assumed the shape given in Fig. 15. The guide G not only overhangs the blank, but it presents a vertical face, 9, between which and the bender F the wire is pressed into Said overhanging portion is beveled off at its vertical side, as illustrated at a, so that as the point of the blank passes along such beveled portion the bent-up end .70 may assume a plane slightly oblique and lateral to the true vertical. This is desirable, as it leaves the point in better position for the succeedingoperations, and obviates the providing of holding devices for insuring the proper position of the bent-up ends of the blank. The guide E is shaped to give this same peculiarity to the other point of the blank, and

for the same reason.

The next operation in order is bending down the as end of the preceding blank A, and this is done by the forwardly-projecting point of the pivoted reciprocating hook H, which is carried by a yoke-slide, I, having bearings at each end of the machine, and actuated by the crank I and In order to insure contact by the forward point of the hook with the vertical end of the blank A, I place at either side of said hook yielding guides J J, pivoted at their rear ends and pressed toward the line of motion of the hook at their forward ends by springs j, the purpose of the pivoting and spring features being to permit the guides to yield as the number of folds in the blank increase and require more room. The hook H continues its forward movement,'and next engages with the blank A, and carries it forward in a line at right angles to the line in which it was first fed in. In so doing the blank is caused to double upon itself, because the hook in such continued movement enters the narrow passage-way J between the guides J, which are furnished with downward projections j on their forward ends, forming the sides of said passage J. Before this bend commences, however, the oscillating bender F, as well as the moving knife and bender E, have been returned to their normal positions below the plane of the feed. The blank A is now bent to the form of a link, as shown at the left of Fig. 16, with its points past each other, and lies in a plane at right angles to that in which it was first fed into the machine. It is allowed to remain in this position during the feeding in, cutting off, and upward bending of the ends of the next blank A, said blank A having been fed over blank, A, so as to lodge in the angle thereof, as shown in said Fig. 16.

It should be noticed that when the hook begins its operation upon the blanks they sink from the level'of the cross-feed, by which they enter the machine, to the bottom of the groove H in the yoke-slide, such groove being the depth of the diameter of the wire. This allows the following blank to be fed over, as just stated. A guide, of thin metal, H", is placed over the hook H and in line therewith, the function whereof is the prevention of any tendency by the points to cross from one side of the link to the other, or, in other words, torotate or twist past each other. The slide I, having completed its forward movement, immediately returns, and this return movement frees the hook H from the wire, and it is allowed to drop by its gravity below the level of the wire, and thereby avoid interference with the blank A during its backward travel. As soon, however, as the hook has retracted to the rear of said blank A, it is forced upward again to the proper plane for its next operation by the cont-act of the arm or trip h, depending from its rear portion, with the spring-bolt h, having a coiled spring, h encircling it, and confined between a collar upon the bolt and the stationary bearing, in which one end of the bolt slides.

The next operation upon the blank A is the bending down of its 00 end by the hook H in the same manner that the end of the link A was bent down by said hook, as previously described, and a like continued forward motion of said hook ensues and doubles the blank A in the same manner as the link A has already been doubled. The links A and A are now ready for the action of the coiling devices, and are moved toward the same intermittently by the feeding-jaws K, (assisted incidentally by latorally'h'o-m opposite V head carries a coiling-point, at, and also a ol the link and insure gancshingwith said segments of the toothed t-euds of the rocking ver said lover being devices, ana wliich anioma-ticzd ly open .to al from tb'eso aws to the sprocket-wheel L, which above ils'oontcr, as shown drel, which seize the link: in close 'i HOXlIYIlIZy cling the mainlrels.

Those jaws are beveled off at the top, oro'pivotcd at It, and arouuder the influenceof spring-sic, so that theyoj' ieneasily to the barbs. As soon as the cable passes on its wayto. the spoolor is located in alower plane, the pull upon the cable tends to force it between these jaws, but it' doe's not enter between the some. for enough tooause entanglement with the projecting points of the cable. The jaws K are placed in tho-yolcc-slido I, so that they are simultaneoua in their movements with the book 11.
